He noticed there are a ton of AI design tools for website such as lovable ai and so he decided to niche down into apps instead, an area of development that is usually overlooked in the Saas space.

He built Sleek in 3 weeks. Sleek is built for founder who want to desing their apps quickly. He noticed there is a growing trend in people who wanted to develop apps and create a way to "vibe design" amazing appa in minutes just by chatting with AI.

In less than a month Sleek reached $10K without spending a single dollar on marketing.

Tech Stack

Sleek was built using Nextjs, Supabase for the backend, Vercel for hosting, Posthog for analytics, Stripe for collecting payments from users, and Resend for sending emails at scale.

100% Organic marketing

Sleek acheived this with an unbelievable total amount spent on marketing of (Drum roll): $0. Mattia made a post on X with a strong hook, a good demo, and asked people to comment for early access. This works great because the X algorithm loves comments.
